Note: Nothing in the specification supersedes applicable laws and regulations unless specific exemption has been obtained.
Note: In the event of conflict between the English and domestic language, the English language shall take precedence.
This test method shall be used to determine the effects of humidity ageing on cellular materials. The test attempts, by the use of water vapour at elevated temperature, to simulate the naturally occurring effects of oxidation and hydrolysis. Deterioration of the material is observed by measurements of physical properties prior to and after ageing.
